Pentair Controllers for Control Valves

Intelligent Control for Optimum Water Treatment

Controllers for Pentair control valves represent the latest generation of intelligent water-treatment technology. AQUA HUB GROUP offers the complete range of Fleck and SIATA controllers, which work seamlessly with the corresponding control valves. These advanced control units form the core of modern water-treatment systems and make the difference between a standard installation and a highly efficient, custom-programmed system.

The Fleck NXT2 Controller is the newest addition to the Pentair portfolio and offers unprecedented flexibility and ease of use. With its large, backlit LCD display and intuitive menu navigation, programming is easier than ever. The NXT2 supports both time-clock and volumetric regeneration and can be configured for single-tank, twin-tank and parallel system configurations. The built-in diagnostic and troubleshooting functions make maintenance and problem-solving a breeze.

The Fleck SXT Controller is the proven industry standard for residential and light commercial applications. This reliable controller offers all the essential functions for efficient water softening and filtration, including adjustable regeneration times, variable backwash cycles and automatic fault detection. The SXT is compatible with the full range of Fleck control valves and is the perfect choice for installers who value reliability and simplicity.

For the most demanding applications, Pentair offers the Fleck XTR/Hurricane Controller. This industrial controller is designed for commercial and industrial installations where continuous operation and advanced programming options are essential. Hurricane technology ensures powerful, efficient regeneration that maximises the service life of the ion-exchange resin and minimises water and salt consumption.

The SIATA SFE Controller range offers a European alternative with advanced features. The basic SFE Controller is ideal for standard residential installations, while the SFE-EV Viridion controller offers Wi-Fi connectivity for remote monitoring and operation via smartphone or tablet. The SIATA SFE-EV PRO is the professional choice for installers who want to offer their customers a premium service, with extensive diagnostics, push notifications and cloud-based data storage.

The Autotrol Easy-iQ control system deserves special mention as a revolutionary platform that unites six different controllers in one universal solution. This means installers can operate all Autotrol valves with a single control unit, which reduces stock costs and simplifies installations. The Easy-iQ offers intuitive programming via a colour touchscreen and supports multiple regeneration modes.

At AQUA HUB GROUP, we not only supply Pentair controllers, but also provide technical support for programming and configuration. Our experts can help you optimise regeneration settings for your specific water composition and consumption pattern. This results in lower operating costs, less salt and water consumption, and a longer service life for your water-treatment installation. Contact us for tailored advice.

Frequently asked questions about Pentair Controllers

What is the difference between the Fleck NXT2 and SXT controller?

The Fleck NXT2 is the latest-generation controller with a larger display, more programming options and improved diagnostics. The SXT is the proven industry standard that offers all the essential functions for reliable water treatment. The NXT2 offers extra flexibility for complex installations, while the SXT is ideal for standard residential applications. Both controllers are compatible with the Fleck valve range.

Can I operate my Pentair controller remotely?

Yes, the SIATA SFE-EV Viridion and SFE-EV PRO controllers offer Wi-Fi connectivity for monitoring and operation via smartphone or tablet. You can start regenerations, adjust settings and check the status of your water-treatment system wherever you are. For Fleck systems, add-on modules are available that offer similar functionality.

How do I programme a Pentair control valve controller?

Pentair controllers have intuitive menu-driven interfaces that make programming easy. The key settings are: current time, regeneration time, regeneration frequency (for time-clock systems) or capacity (for volumetric systems), and regeneration cycle duration. Each controller comes with a comprehensive manual. AQUA HUB GROUP also offers technical support for programming.

What do the error codes on my Pentair controller mean?

Pentair controllers display error codes for problems such as motor faults, sensor problems or power interruptions. The manual supplied with your controller contains a complete list of error codes and solutions. Common codes relate to the position encoder, water meter or power supply. If problems persist, we advise contacting AQUA HUB GROUP for diagnosis and support.

How long are settings retained during a power cut?

Modern Pentair controllers feature non-volatile memory (EEPROM) that retains settings permanently, even during prolonged power cuts. The internal clock is usually backed up by a battery or supercapacitor that keeps the time for 24 to 72 hours. After a longer power cut, only the time may need to be reset; all other programming is retained.

Is the Autotrol Easy-iQ compatible with all Autotrol valves?

Yes, the Autotrol Easy-iQ system is designed as a universal controller for all Autotrol valves, from the compact 255 Series to the industrial Magnum Series. This simplifies stock management for installers and guarantees compatibility for replacements. The Easy-iQ automatically detects the valve type and adjusts the available functions.

What is the advantage of a touchscreen controller?

Touchscreen controllers such as the Autotrol Easy-iQ and SIATA SFE-EV offer more intuitive operation, better readability and more advanced programming options. Graphical displays make it easier to interpret system status and historical data. Touchscreens are also less susceptible to wear than mechanical buttons, which benefits the service life of the controller.

Can I use a controller from another brand on my Pentair valve?

We strongly recommend using only genuine Pentair controllers with Pentair valves. The controllers are specifically designed for the mechanical and electrical characteristics of the corresponding valves. Using non-compatible controllers can lead to incorrect operation, damage or loss of warranty. AQUA HUB GROUP supplies only genuine Pentair controllers.

How often should I replace the battery in my controller?

The internal back-up battery of Pentair controllers has a service life of 3 to 5 years under normal conditions. Some controllers use a rechargeable supercapacitor that does not need replacing. If the controller no longer keeps the time after a power cut, this indicates that the battery is due for replacement. AQUA HUB GROUP supplies replacement batteries for all Pentair controller models.

Where can I buy Pentair controllers?

AQUA HUB GROUP is the official Pentair distributor in Belgium for the complete range of controllers. We supply Fleck NXT2, SXT and XTR controllers, Autotrol Easy-iQ systems and SIATA SFE controllers. All controllers are supplied with a Dutch-language manual and technical support. Contact us for advice and a competitive quote.
